Patented Apr. 14, 1931 EDWARD MGKUEN, OF MADERA, CALIFORNIA LUMBER-LOADING DEVICE Application filed April 17,

My present invention relates to an improved lumber loading'arrangement and more particularly to apparatus for conveniently handling lumber as it is turned out at the saw mill.

, An object of my invention is to provide a new and novel arrangement of apparatus for the convenient handling of sawed lu1nher and the like. y

A further object of my invention is to provide apparatus which is particularly well adapted to the handling of lumber as it is turned out at the saw mill.

.In the past, various types of collapsible supports have been provided for handling lumber as contemplated by my invention, but these supports have met with very little application asthey are in most cases very complicated and expensive, and also because of the fact that they are not as-readily adapted to the particular use contemplated.

In carrying out my invention, I propose to provide an arrangement which can be built in as a part of the saw mill loading platform and which will be reliable, cheap,

and simple inits operation.

For a better understanding of my invention, reference should be had to the accompanying drawing, wherein I have. shown by way of illustration andnot oflimitatioma preferred embodiment of myinvention.

, In the drawing- Fig. 1 is a View in elevation, partially in section. showing my device supporting a load of lumber, and I Fig. 2 is a fragmentary view, partially in section, showing two loading stations with the lumber in its unloaded and loaded positions.

In Fig. 1 of the drawing, designates a pile of sawed lumber which is about to be taken away from the saw mill; 11 designates a suitable platform built upon and forming a suitable part of the saw mill; and i2 designates a suitable lumber supporting car such as is commonly used in this art. The platform 11 is shown'as having an inclined extension 13 for1ned as a part thereof, and spaced away from the platform and ar- 50 ranged parallel therewith there is shown 1928. Serial No. 355,737.

pair of pedestals 14. These pedestals 14 are arranged on opposite sides of a suitable trackway 15 and serve to support a suitable beam '16. In the present instance this beam 16 is shown as comprised of a length of railway rail. The rail 16 is of sutlicient length to bridge between the pedestals 14 and serves in co-operation with the platform 11 to form a support for the sawed lumber, the lumber being supported in this manner at a height sufficient to permit an empty car 12 to be placed thereunder. The top of the pedestal 1 1 is cut away in any suitable fashion as at 17 so that the rail 16 may be dislodged from the pedestals by a simple tipping operation, the tipping operation being carried out by means of a cant hook or wrench 18, in the hands of an operator. With this arrangement it will be seen that when the operator pulls down upon the cant hook 18, he will cause the lumber 10 to move outwardly over the incline 13 upon the platform 11, the rail at the same time sliding down off of the pedestals 1 so as to permit the load of lumber 10 to fall as a whole upon the car 12, the rail 16 during this operation falling down free from the lumber where it can be removed to permit the movement of the car 12 with its load of lumber to any suitable point. 80

It will also be seen that, with this arrange ment, the number of cars required at any particular station will be greatly reduced as the load of lumber can be made up as the car is in use taking a previous load of lumber to an unloading point.

Asa safety precaution, I have also shown a stay or strut 19 which may be interposed in any suitable manner between the road bed 9 and the rail 18to prevent its d'islodgment accidentally.

By referring to Fig. 2 of the drawing, it will be seen that with the above arrangement, the trackways may be placed very close together and that only a single pedestal 14 will be required between the trackways, thus making it possible to space the trackways very close together. In this figure of the drawingl have shown on y two trackways,

but it is to beundeistood that contemplate if f {that any number of i 'suchtrackways may be provided. I While I have shown froin the spizit ofthe inventionasdefinedin the appended elaimsg as for."instaiiowwhile I have describedin the specification and-illustrated in the drawliggs, ,.ti aokways zforvthe,
